. l CALIFORNIA .Application led January `9, 1929. Serial No. 331,184.

rlhis invention relatesto a device adapted particularly for use in connection with the` sucker rods and tubingin an oil well pumping organization. It is well known to those familiar with the art that incertain types of crude petroleum which contain a large percentage of wax or asphaltic compounds, that these compounds tend to deposit and accumulate upon the inner surface of the tubing through which the petroleum is removed from the well and upon the rods actuating the pumping device. n '1 1'; Itis aprima'ryfobject ofthi's invention to produce a device of simple form and construc-A tion embodying an improvement upon the organization disclosed in our copending application, Serial No. 278,758, which is reciprocably and rotatably mounted upon the sucker rodand is so formed as to scrape the inner surface lof the tubing andthe outer surface of the "rods, and prevent the deposition of solidmaterials as mentioned above.

Itis also an object of this invention to produce an organization of the class described which will; function as'aguide for the sucker rod, preventing the 'rod from engaging the inner surface of the tubing. The guide being n reciprocable' as mentioned above, the wear between the reciprocating members and the tubing is materiallyl reduced ydue to the factthat this wear is distributed over a much greater areathan inthecase where the sucker rod it' self rests upon the inner surface of the tubing and for the same reason the wear. on the Sucher rodsl isfmuch less than would be the case inthe vuse of fixed guides.

In the organization disclosed' in our co y pending applicatiomthe scrapingl guides are formed 1n a manner such that it'isnecessary, 40 1n order to place them upon the sucker rods,

either` to 4place the guides upon the rods durlngl the manufacture of the rods or to severY thesucker Vrods and re-splice them for each Section :that carries one or more of the guides. .5 Itis tle'primary 'object of thisY invention to develo'pfan organization in which this feature' is overcome b making the Aguides in two or'moresectionsw ich a're adapted to be held' 1n co-operativeengagement by members such as threaded collars.

The details in the construction of this invention, together with further objects attending its production, will be better understood from the following description of the accompanying drawings, in which 55 Fig. 1 is an elevational view partly in section showing a tubing member having-a sucker rod equipped with an embodiment of the invention suspended therein.

Fig. 2 is a perspective view illustrating a 60 preferred embodiment of the invention.

'Fig 3 is a plan view which may be considered as having been taken substantially in a plane represented by the line 3 3 in Fig. 1.

Fig. 4 is a partial sectional elevation which c5 maybe considered as having been taken in a plane represented by the line 4 4 in Fig. 3.

Fig. 5 is a sectional elevation which may be considered as having been taken in planes represented by the lines 5 5 in Fig. 3. y 70 Fig. 6 is a detached partial sectional elevation illustrating the construction of a preferred form of joint between a blade and i, bearing member.

The general construction of this invention embodies a plurality of blades which are preferably formed as partial spirals adapted to scrape the inner surface of the tubing and the outer surface of the rods and are symmetrically arranged about an axis which is 8o concentric with that of the sucker rod upon which the guide is mounted. The ends of these blades are suitably mounted in bearing members, such bearing members being in the form of co-operating sections which Aare adapted to be held in assembled relationship by means such as threaded collars. v d

` More particularly `describing the invention as herein illustrated, reference numeral 11 indicates Can .oil well tubing adapted to re- 9o ceive a'sucker rod 12 com rising sections 12' and'12b`which are unite .by means of the couplingsv indicated at 12. he'sucker rods are illustrated' as being of the standard form commonl usedtin oil well pum ingopera- 95 tions, an vthe scra ing guides em odying ourinvention 'are indicated enerally by referencen'lllflieral, and`in F1g.1 are illustrated as beinginounted upon the sucker rod 12.

The details in the construction of the scrapformed, terminates in an outwardly extending flange or shoulder 18.

The flange or shoulder 18 is provided with a plurality of notches indicated at 19 and the hub section 17 is provided with a plurality of recesses 20 which co-operate with the notches 19 to receive the ends of the'blade members in the manner best illustrated in Figs. 4 and 6.

It will be noted in Figs. 4 and 6 that the end 21 of each blade member 14 is provided with an outer notched section indicated at 22 and an inner notch indicated at 23. The inner notch 23 is adapted to receive a proj ection 24 which is formed upon the bearing member by notch 19 and recess 2O in the flange 18 and the hub member 17 respectively. In order that this construction may be made more rigid, it is preferable to unite the blades with their respective bearing segments by means such' as welding or soldering. The segments 16 and 16 together with the blades supported therein are held in assembled relationship by means such as an internally threaded collar indicated at 25, and in order that the organization may be assembled upon the sucker rod, the collars 25 must necessarily be of greater inside diameter than the outside diameter of the couplings 12C.

In the form of the invention chosen for the purpose of description, the top and bottom bearing members being identical, the elements of these members are indicated by the same reference numerals and as was ment1oned in connection with our (zo-pending applicationit is a feature of this invention to so form an organization that the passage of fluid in the tubing tends to rotate the scraping guideon the sucker rod. This is accomplished by providing a plurality of apertures 26 in the hub sections 16 and- 16. such apertures being formed in a manner such that the fluid passing therethrough is impinged against the spiral surface of the blade oppo-` site the aperture. This How of fluidl through the apertures 26 imparts a rotative movement to the blades and assures a more eflicient scraping action against the inner surface of th? tubing, and the outer surface of the sucker ro s.

It will be understod that while we have herein described and illustrated one preferred embodiment of this invention that the invention is not limited to the precise construction setforth, but includes within its scope such changes as may fairly come within the spirit of the appended claims.
